Product Description

20mm 28mm 33mm 40mm Medium Voltage Cross Linked Polyolefin Bus BarTubing      

 

is made from specially formulated radiation cross-linked halogen free compounds. It can provide high resistance to tracking and arcing, as well as to enhance the insulation properties of bus-bar in switchgear and substation. Suitable for application in insulating medium voltage bus bars, cable termination and joints from 1KV to 24KV.

 

 

Features      

 

•  Flame Retardant

 

•  Reduces bus bar clearance requirements

 

•  Protect against accidental flashover

 

•  Anti-track

 

•  Halogen free

 

• Tested to IEC60684 standards for medium voltage switch-gear applications to above 20KV

 

•  Continuous Operating Temperature:

 

-40 °C to 110°C, can be used in 175°C

 

•  Shrink Temperature: 120°C
